Especially during summer, it is essential to check your vehicle’s anti-freeze once a month.
You should periodically change the radiator fluid in your vehicle to help your car’s cooling system function at its best. Over time, dirt and other contaminants can build up in the fluid, or it may become acidic. When this occurs, the radiator fluid is much less effective and should be changed.
Most car manufacturers recommend that you change the radiator fluid in your vehicle every 24,000 to 36,000 miles, or every 24 to 36 months. However, your personal driving habits will also determine the frequency of needed radiator fluid changes. If you drive your vehicle in extreme extremely hot temperatures often, you may want to consider changing the fluid once a year or every 12,000 to 15,000 miles.
